Brake Applying Devices .Be it known that I, HARRY P. ZACKEY, a

- [citizenof the United States, residing at Martinsville, in the countyof Niagara and State of New York, have invented certain new and usefulImprovements in Automatic for Railway- Trains; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

' This invention relates to improvements in automatic brake applyingdevices for steam, electric, or compressed air railway trains.

The object of the invention is to rovide a device of this character bymeans 0 which the brake operatin mechanism of a train will be automaticaly actuated should the train for any reason run into an open switch orpass a danger signal.

'A further object is to provide an electric controlling device for thebrake operating .mechanism of a train which will be set for .operationby the opening of a switch or the movement of a semaphore ordangersignaland which will be simple in construction positive and reliable inoperation.

'With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claim.

In the accompanying drawings, Figure 1 is a diagrammatic perspectiveview of a portion of a locomotive and a part of a railway track showingthe application of the invention; Fig. 2 is a side view of a portionof'a railway track, showing the manner in which the electric operatingmechanism is protected from .the weather; Fig. 3 is an end viewof the"electro-magnet protecting box or casing showing the cover operatingmechanism thereof in an inoperative position and the cover closed; Fig.4 is a similar; view showing the manner in which the cover cratingmechanism is actuated to open the cover of the box.

Referring more particularly to the drawings, 1 denotes a portion of thecab and rear end of the locomotive, and 2 denotes the railway track.Arranged in the cab of the locomotive, is the usual engineers brakevalve 3 which connects with the train air pipe 4 and the whistle airp1pe 5 (see Flg.

. locomotive, as shown.

1) whereby the air in said pipes is controlled to operate the brakes andthe whistle in connected by a pivotally mounted lever 10 to an operatingrod 11 which is slidably mounted in a suitable guide bracket 12 securedin proper position on the'sideof the On the lower end of the rod 11 isarranged a steel block 13 which forms the armature of an electro-magnet14 hereinafter described. The upper end of the operating rod 9 extendsupwardly and projects into the cab and is provided with an operatinghandle 15. of the rod 9 which projects into the cab is provided with aseries of ratchet teeth 16 with which is adapted to be engaged a holdingpawl 17 which is pivotally mounted. in the cab, as shown, and is adaptedto be released or disengaged from the ratchet teeth The upper portion 16by the hand or foot of the engineer to permit the operating rod to beforced downwardly to an operative position for closing the angle cock7-.

The electro-ma-gnet 14 comprises a bar 18 which is connected with aseries of magnet coils 19 whereby said bar 18 is magnetized when thecoils are energized. The coils are arranged'in an electric circuit 20which may be connected with any suitable batteries 21 or with any othersource of electrical sup- .ply. In the circuit 20 is also arranged aswitch or circuit closer (not shown), but which is adapted to beoperated by the movement of a switch or the operation of a danger signalwhereby the circuit 20 will plying the brakes. When the operating rod 9has thus been projected upwardly, the

pawl v17 will play looselyover the ratchet teeth and will hold'the rodupand the angle cock open until released by the engineer or other personin the manor described.

In connection with the-magnet coils l9 and bar 18, I provide a hog; orcasing 22 whereby phi said coils and bar are protecteci from snow orice. The box or casing 2.2 is "provided with a cover 23 which is hingedto the outer upper edge of the box anfl has connected to its hinged edgeoperating links 2 the lower ends of which are connected to segmentalgears pivot-ally mounted on the opposiee ends of the box 22 and inoperative engagement with similar gears 26 also pivoted on the ends ofthe no. and which are connected with an operating plate 01" bar 2?arranged. on the inner side of the box adjacent to the outside edge ofthe track rail anci projecting at a suitable distance above the same andin position to be engaged by he ireaei of the locomotive Wheels wherebywhen the forward wheels of the locomotive pass over said or plate 2?,the same Wiii be depressed which in turn will operate the gears 25 andswing Lhr) cover of the box to an open position to eirgose the magnetbar 18 so that it will attract the armaeure biock 13 and operate the airreleasing mechanism in the manner hereinbefore described. The segmentalgears 25 anti 26 are provide with coil springs 28 which are adapted toactuate the same to close the COYGL of the box after Jhe train haspassed oYer the same. v

From the foregoing description, taken in conneen with the accompanyingdrawings,

the constrgctic n an. operation of the inveniion, will be z'eaciilyunderstood With-0171i) requiring a more extendeci'expianaiion.

Various changes in she form proposition and the minor detailsconstruction may be resorted to Without departing from flee principie orsacrificing any 01' the advantages of the invention, in. iii-e appended. claim. 1 4;

Having thus. ciescribed zn inaenion, What I cieim is:
